[0037] This disclosure presents a communication method, communication device, and communication system.

[0038] In a first aspect, embodiments of this disclosure provide a communication method applied to a first access point (AP), the method comprising:

[0039] A first radio frame is determined; wherein the first radio frame is used to: deactivate the dynamic unavailable DUO operation of the basic service set (BSS) where the first AP is located, and / or deactivate the DUO operation of the BSS where other APs are located.

[0040] Send the first wireless frame.

[0041] In the above embodiments, the first AP determines and sends a first radio frame to deactivate the DUO operation of its own BSS, or to deactivate the DUO operation of other APs' BSSs. In this way, the first AP can promptly cancel or terminate unnecessary DUO operations, thereby freeing up communication resources and avoiding unnecessary network load. This method helps improve network resource utilization efficiency, reduce communication latency, enhance system stability, and achieve more efficient coordination and management in multi-AP environments.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, the first wireless frame includes at least one of the following:

[0043] The first information element indicates the time information for activating the DUO operation;

[0044] A first information field; wherein, the first parameter value in the first information field is updated to identify that the first information element is carried in the first wireless frame or in a frame following the first wireless frame.

[0045] The second information field; wherein the second parameter value update in the second information field indicates that the first radio frame is used to deactivate the DUO operation of the BSS where the other AP is located; the other APs include APs that are attached to the same multi-link access point device (AP MLD) as the first AP;

[0046] The second information element identifies that the first radio frame is used to deactivate the DUO operation of the BSS where the other AP is located; the other APs include the neighboring APs of the first AP.

[0047] In the above embodiments, the first radio frame may contain multiple information elements and information fields. The first information element carries time information for deactivating the DUO operation, specifying when to terminate the operation. An increase in the first parameter value in the first information field indicates that the frame or a subsequent frame will contain information related to deactivating the DUO operation. An increase in the second parameter value in the second information field indicates that the frame is used to deactivate the DUO operation of other APs in the BSS, especially when other APs and the first AP belong to the same multi-link access point device (AP MLD). The second information element explicitly identifies that the frame is used to deactivate the DUO operation of neighboring APs in the BSS. In this way, the first AP can flexibly control the activation and deactivation of the DUO operation, which helps to save resources and improve network efficiency and stability.

[0048] In conjunction with some embodiments of the first aspect, in some embodiments, the time information is determined based on the target beacon transmission time (TBTT) for the first AP to pre-transmit beacon frames, and / or the transmission period of the beacon frames.

[0049] In the above embodiments, the timing information for deactivating the DUO operation carried by the first information element is determined based on the Target Beacon Transmission Time (TBTT) or the transmission period of the beacon frame scheduled for transmission by the first AP. In this way, the first AP can activate or deactivate the DUO operation according to the predetermined timing of its beacon frame, thereby synchronizing its beacons with those of other APs and ensuring network coordination and efficient resource utilization.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the first information field includes at least one of the following:

[0051] Basic Service Set (BSS) parameters change field and check beacon field.

[0052] In the above embodiments, the use of the information domain can better coordinate the allocation of wireless resources in a multi-AP environment, ensuring more stable network operation and reducing conflicts and interference.

[0053] In conjunction with some embodiments of the first aspect, in some embodiments, when the first radio frame includes a first information element and a second information field, the first information element is included in the STA profile field of the first radio frame, and the second information field is included in the multi-link element of the first radio frame.

[0054] In the above embodiments, when the first radio frame contains a first information element and a second information field, the information carried by the first information element is placed in the Site Device Profile (STA profile) field of the first radio frame. This profile typically contains the device's configuration parameters and capability information, providing information about the functions and statuses supported by the AP or device. The second information field is carried in the multi-link element of the first radio frame, used to identify link information related to the multi-link access point device (AP MLD), such as link status and link type. This structure ensures that the first radio frame transmits the necessary device configuration and link information, facilitating more flexible and efficient multi-link cooperation, optimizing network resource allocation, and improving system stability and efficiency.

[0055] In conjunction with some embodiments of the first aspect, in some embodiments, when the first radio frame includes a second information element, the timing information for deactivating the DUO operation of the BSS where the neighboring AP is located is carried in the beacon frame or probe response frame sent by the neighboring AP.

[0056] In the above embodiments, when the first radio frame contains the second information element, the information carried by the time information for deactivating the DUO operation of the BSS where the neighboring AP is located is embedded in the beacon frame or probe response frame sent by the neighboring AP, so that the receiving end performs a response operation according to the time information sent by the neighboring AP.

[0057] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes one or more of the following:

[0058] Before the start time of the deactivation DUO operation indicated by the first radio frame arrives, the DUO operation is performed in the transmission opportunity TXOP with the site equipment STA that has already activated the DUO operation;

[0059] If the time period corresponding to the DUO operation overlaps with the time period of the deactivation DUO operation indicated by the first radio frame, and the overlapping time period is within TXOP, then the first AP will not perform the deactivation DUO operation during the overlapping time period.

[0060] If the deactivation of DUO has not yet taken effect, and the first AP sends a DUO activation frame to the STA, the DUO activation frame indicates that the first AP refuses to activate the DUO operation.

[0061] In the above embodiments, after sending the first radio frame, the first AP can perform one or more of the following operations: First, before the start time of the deactivation DUO operation identified by the first information element arrives, the first AP will continue to perform DUO operations with the station equipment (STA) that has already activated the DUO operation during the transmission opportunity (TXOP). This means that even though the deactivation operation has been requested, the first AP will maintain the DUO operation until the predetermined time point arrives. Second, if the time period of the ongoing DUO operation overlaps with the time period of the deactivation DUO operation in the TXOP, the first AP will not immediately deactivate the DUO operation during the overlapping time period, but will continue to maintain the current operation state until the time period ends or other conditions are met. Finally, if the deactivation DUO operation has not yet taken effect, and the first AP decides to send a DUO activation frame to the STA, this frame will explicitly indicate that the first AP refuses to activate the DUO operation. Through these operations, the first AP can flexibly control the activation and deactivation time of the DUO operation, avoid operational conflicts or resource waste, thereby improving network efficiency and stability, and ensuring the continuity and reliability of communication.

[0062] In conjunction with some embodiments of the first aspect, in some embodiments, the first wireless frame includes at least one of the following:

[0063] beacon frame, association response frame, reassociation response frame, probe response frame.

[0064] In the above embodiments, these frames can carry control information related to DUO operation, which helps to achieve effective coordination between AP and device, ensure smooth and efficient communication in a multi-AP environment, and reduce conflicts and interference.

[0065] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0066] Determine the second radio frame, the second radio frame identifier being: the first BSS parameter after deactivating the DUO operation of the BSS where the first AP is located, and / or the second BSS parameter after deactivating the DUO operation of the BSS where the other APs are located;

[0067] Send the second wireless frame.

[0068] In the above embodiments, this operation can effectively synchronize the status of each AP in the network, ensuring that the network configuration is quickly updated after the DUO operation deactivates it, thereby improving the utilization efficiency of network resources, reducing conflicts and interference, and ensuring the continuity and stability of communication.

[0069] In conjunction with some embodiments of the first aspect, in some embodiments, the first BSS parameter or the second BSS parameter includes at least one of the following:

[0070] Bandwidth (BW), maximum physical layer protocol data unit (PPDU) length, and maximum media access control protocol data unit (MPDU) length.

[0071] In the above embodiments, by transmitting these key BSS parameters in the second wireless frame, the first AP can notify other APs or devices of the new network configuration after the DUO operation is deactivated, ensuring that network resources are optimized, improving data transmission efficiency, and reducing latency.

[0072] Secondly, embodiments of this disclosure provide a communication method applied to a STA, the method comprising:

[0073] Receive a first radio frame; wherein the first radio frame is used to: deactivate the DUO operation of the BSS where the first AP is located, and / or deactivate the DUO operation of the BSS where other APs are located.

[0074] In conjunction with some embodiments of the second aspect, in some embodiments, after receiving the first radio frame, the method further includes:

[0075] Receive a second radio frame, the second radio frame identifier being: the first BSS parameter after deactivating the DUO operation of the BSS where the first AP is located, and / or the second BSS parameter after deactivating the BSS where the other APs are located.

[0111] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0112] As shown in Figure 1, the communication system 100 includes a first access point device (AP) 101 and a station device (STA) 102.

[0113] In some embodiments, the site device 102 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi communication. Optionally, the wireless communication terminal may be at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports Wi-Fi communication, a car with Wi-Fi communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home.

[0114] Specifically, site device 102 can be a terminal device or network device with a Wi-Fi chip. Optionally, site device 102 can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.

[0115] In some embodiments, the first access point device 101 can be an access point for mobile terminals to access a wired network. An AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to an Ethernet network. Specifically, an AP can be a terminal device or network device with a wireless fidelity chip. Optionally, the AP can support various WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next-generation 802.11 protocol, but is not limited to these.

[0116] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple links. For example, they can be represented as Access Point Multi-Link Device (AP MLD) and Non-Access Point Multi-Link Device (non-AP MLD), respectively. AP MLD can represent an access point that supports multi-link communication functions, and non-AP MLD can represent a site that supports multi-link communication functions. For example, in this embodiment of the disclosure, link can represent connection or link; in various embodiments, connection and link can be interchanged.

[0117] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0118] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0119] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called the Access Point (AP) device, and all other STAs in the network are associated with it. Other sites in the BSS network that are not the central site are called terminals, also known as non-AP STAs; terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between terminals and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.

[0120] Figure 2 is one of the interactive schematic diagrams of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0121] Step 201, the first AP 101 determines the first radio frame; wherein, the first radio frame is used to: deactivate the Dynamic Unavailability Operation (DUO) of the Basic Service Set (BSS) where the first AP 101 is located, and / or, deactivate the DUO operation of the BSS where other APs are located.

[0122] In the UHR (Unified Wireless Response System), to further improve the reliability of WLAN connections, and considering that devices may also support other services such as Bluetooth (BT) or Ultra Wide Band (UWB), an In-Device Coexistence (IDC) mechanism is proposed. The IDC mechanism aims to optimize the coexistence of multiple communication technologies in a wireless network to reduce interference and improve overall performance. The IDC mechanism includes two types: bursty and periodic. The bursty IDC mechanism is used to quickly respond to instantaneous changes in the wireless environment, especially in environments where multiple devices or communication protocols work together. To further improve spectrum utilization efficiency and reduce interference, the bursty IDC mechanism introduces a DUO (Delayed Operation) mechanism. DUO refers to a state where a device is temporarily unable to provide Wi-Fi service due to the need to handle bursty service demands (e.g., Bluetooth communication). In other words, Wi-Fi availability is affected, requiring temporary "disabling" or making Wi-Fi communication unavailable to prioritize other urgent or bursty service demands.

[0123] In the DUO operation mechanism, a STA can request activation of the DUO operation mechanism from its associated AP by sending a DUO activation frame. If the AP accepts the request and agrees to perform the DUO operation, it will reply with a DUO activation frame, thereby initiating the corresponding resource management policy to prevent network resource conflicts and interference. Similarly, an AP can also proactively send a similar DUO activation frame to a STA to request activation of the DUO operation mechanism. If the STA accepts the request and agrees to perform the DUO operation, it will reply with a DUO activation frame. However, in practical applications, there is still a lack of unified standards and clear decision-making mechanisms for how to reject DUO operation requests or, in certain situations, deactivate already activated BSSDUO operations. Therefore, the embodiments disclosed in this disclosure aim to further improve the mechanism for deactivating DUO operations to adapt to UHR transmission requirements.

[0124] In this embodiment, the first AP determines a first radio frame, which includes at least one of the following: a beacon frame, an association response frame, a reassociation response frame, and a probe response frame. The first radio frame is used to deactivate the DUO operation of the BSS where the first AP is located, and / or deactivate the DUO operation of the BSS where other APs are located. The first AP and other APs can be various types of devices. Specifically, the first AP typically refers to a wireless access point (AP) in the network, which can be an AP attached to an AP MLD. Other APs can have different scenarios. For example, if other APs are non-transmitted APs, the deactivation information for DUO operation is carried in the multiple BSSID set information elements of the first radio frame. If other APs belong to the same AP MLD as the first AP, the deactivation information for DUO operation can be transmitted through multi-link information elements, and the deactivation operation for DUO operation is performed on the link to which the other AP belongs. If the second AP is a neighboring AP (i.e., a physically isolated AP), the first radio frame carries the deactivation DUO operation information of the neighboring AP. The deactivation DUO operation is performed by the neighboring AP in its BSS. Optionally, the deactivation DUO operation information of the neighboring AP can be carried by defining a new information element. Through the deactivation DUO operation, the first AP and / or other APs can restore normal resource usage and avoid interference caused by simultaneous communication between Wi-Fi services and IDC services (such as Bluetooth), which could lead to unstable reception or failure to decode, thus wasting resources.

[0125] Step 202: The first AP 101 sends the first wireless frame; correspondingly, the STA 102 receives the first wireless frame.

[0126] In this embodiment of the disclosure, the first device sends the first radio frame, which is used to deactivate the DUO operation of the BSS where the first AP is located, and / or deactivate the DUO operation of the BSS where other APs are located, in order to meet the requirements of UHR.

[0135] Figure 3 is a second interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiments of the present disclosure relate to a communication method, which includes:

[0136] Step 301, the first AP 101 determines the first radio frame; wherein, the first radio frame is used to: deactivate the dynamic unavailable DUO operation of the basic service set (BSS) where the first AP 101 is located, and / or, deactivate the DUO operation of the BSS where other APs are located.

[0137] In this embodiment of the disclosure, the first device sends a first radio frame, which is used to deactivate the DUO operation of the BSS where the first AP is located, and / or deactivate the DUO operation of the BSS where other APs are located, to meet the requirements of UHR. By deactivating the DUO operation, the first AP and / or other APs can restore the normal use of resources, avoiding interference caused by simultaneous communication between Wi-Fi services and IDC services (such as Bluetooth), which could lead to unstable reception or failure to decode, thus wasting resources.

[0138] In some embodiments, the first wireless frame includes at least one of the following:

[0139] The first information element indicates the time information for activating the DUO operation;

[0140] A first information field; wherein, the first parameter value in the first information field is updated to identify that the first information element is carried in the first wireless frame or in a frame following the first wireless frame.

[0141] The second information field; wherein the second parameter value update in the second information field indicates that the first radio frame is used to deactivate the DUO operation of the BSS where the other AP is located; the other APs include APs that are attached to the same multi-link access point device (AP MLD) as the first AP;

[0142] The second information element identifies the DUO operation information used by the first radio frame to deactivate the BSS where the other APs are located; the other APs include the neighboring APs of the first AP.

[0143] The first information element can be a newly defined information element used to carry time information for deactivating the DUO operation. For example, the structure of the newly defined information element includes one or more of the following: element ID, length, and a field for carrying time information for deactivating the DUO operation. The time information for deactivating the DUO operation includes, but is not limited to, the start time of deactivating the DUO operation. Updating the first parameter value in the first information field indicates that the first information element is carried in the first radio frame or a frame following the first radio frame. For example, increasing the first parameter value in the first information field indicates that the first information element is carried in the first radio frame or a frame following the first radio frame. Frames sent after the first radio frame include, but are not limited to, beacon frames, management frames, or data frames.

[0144] Optionally, if other APs are non-transmitted APs, the deactivation DUO operation information is carried in the multiple BSSID set information element of the first radio frame. If other APs belong to the same AP MLD as the first AP, the deactivation DUO operation information is carried in the multi-link element information element of the first radio frame. If the second AP is a neighboring AP, the deactivation DUO operation information of the neighboring AP is carried in the first radio frame by defining a new information element.

[0145] In some embodiments, the time information is determined based on the Target Beacon Transmission Time (TBTT) of the first AP's predetermined beacon frame transmission and / or the transmission period of the beacon frame.

[0146] In this embodiment of the disclosure, the timing information for deactivating the DUO operation carried by the first information element is determined based on the TBTT (Transmission Time To Beam) and / or the transmission period of the beacon frame scheduled by the first AP. Specifically, the timing information for deactivating the DUO operation may be related to the TBTT, or to the transmission period of the beacon frame, or both. For example, the timing information may be an integer multiple of the TBTT or the beacon frame period. This means that the first AP can precisely schedule the deactivation timing of the DUO operation based on the transmission time or period of its beacon frames, thereby ensuring that network resources and channels can be restored to normal use at the appropriate time.

[0147] In some embodiments, the first information field includes at least one of the following:

[0148] Basic Service Set (BSS) parameters change field and check beacon field.

[0149] In this embodiment of the disclosure, the first information field includes, but is not limited to, a Basic Service Set Parameter Change (BSS parameters change) field and a check beacon field. By utilizing the existing BSS Parameter Change field, the first AP can transmit BSS parameter change information without introducing new signaling fields. This reduces protocol complexity and maintains compatibility with existing standards. For example, adding "1" or other values ​​to the parameter values ​​in the BSS parameters change field or check beacon field indicates that the BSS parameters of the BSS where the first AP is located have changed, and the first information element is carried in the first radio frame or a frame following the transmission of the first radio frame.

[0150] In some embodiments, where the first radio frame includes a first information element and a second information field, the first information element is included in the STA profile field of the first radio frame, and the second information field is included in the multi-link element of the first radio frame.

[0151] In this embodiment of the disclosure, the second information field can be a BSS parameter change field, which can be carried in the per-STA profile field of the multi-link element of the first radio frame. The parameter value of the BSS parameter change field is incremented by "1" or other values ​​to indicate that the first radio frame is used to deactivate the DUO operation of the BSS where the AP attached to the same multi-link access point device (AP MLD) resides. Optionally, the time information of the AP attached to the same multi-link access point device (AP MLD) deactivating the DUO operation is carried in the STA profile field of the first radio frame. The second information element includes, but is not limited to, a Reassociation Request Information Element (RNR); the parameter value of the BSS parameter change field in the RNR information element is incremented by "1" or other values ​​to indicate that the first radio frame is used to deactivate the DUO operation of the BSS where the neighboring AP resides.

[0152] In some embodiments, when the first radio frame includes a second information element, the timing information for deactivating the DUO operation of the BSS where the neighboring AP is located is carried in the beacon frame or probe response frame sent by the neighboring AP.

[0153] In this embodiment of the disclosure, when the first radio frame includes a second information element that identifies the first radio frame as being used to deactivate the DUO operation of the BSS where the neighboring AP is located, the neighboring AP may carry time information for deactivating the DUO operation in a beacon frame or a probe response frame.

[0154] In step 302, AP 101 sends the first wireless frame; correspondingly, STA 102 receives the first wireless frame.

[0155] In this embodiment of the disclosure, the first device sends the first radio frame, which is used to deactivate the DUO operation of the BSS where the first AP is located, and / or deactivate the DUO operation of the BSS where other APs are located, in order to meet the requirements of UHR.

[0156] The communication method involved in the embodiments of this disclosure may include at least one of steps 301 to 302. For example, step 301 may be implemented as a standalone embodiment, step 302 may be implemented as a standalone embodiment, and steps 301+302 may be implemented as standalone embodiments, but are not limited thereto.

[0157] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0158] Figure 4 is a third interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the embodiments of the present disclosure relate to a communication method, which includes:

[0159] Step 401, the first AP 101 determines the first radio frame; wherein, the first radio frame is used to: deactivate the dynamic unavailable DUO operation of the basic service set (BSS) where the first AP 101 is located, and / or, deactivate the DUO operation of the BSS where other APs are located.

[0160] In this embodiment of the disclosure, the first device sends a first radio frame, which is used to deactivate the DUO operation of the BSS where the first AP is located, and / or deactivate the DUO operation of the BSS where other APs are located, in order to meet the requirements of UHR.

[0161] Step 402, AP 101 sends the first wireless frame; correspondingly, STA 102 receives the first wireless frame.

[0162] In this embodiment of the disclosure, the first device sends the first radio frame, which is used to deactivate the DUO operation of the BSS where the first AP is located, and / or deactivate the DUO operation of the BSS where other APs are located, in order to meet the requirements of UHR.

[0163] Step 403: After the first AP 101 sends the first wireless frame, it performs any one or more of the following operations from Case 1 to Case 3:

[0164] Scenario 1: Before the start time indicated by the first radio frame arrives, the DUO operation is performed in the Transmission Opportunity (TXOP) with STA 102, which has already activated the DUO operation.

[0165] In this embodiment of the disclosure, before the start time of the deactivation DUO operation identified by the first information element arrives, the first AP continues to perform the DUO operation with the STA that has already activated the DUO operation in TXOP. That is, before the deactivation operation begins, the DUO operation between the first AP and the STA continues normally, unaffected by the deactivation command. This delayed deactivation method ensures that the device only performs IDC service communication before the deactivation operation takes effect, avoiding interference between simultaneous Wi-Fi and IDC service communication.

[0166] Scenario 2: If the time period corresponding to the DUO operation overlaps with the time period of the deactivation DUO operation indicated by the first radio frame, and the overlapping time period is within TXOP, then the first AP 101 will not perform the deactivation DUO operation during the overlapping time period.

[0167] In this embodiment of the disclosure, if the ongoing DUO operation overlaps with the deactivation DUO operation time period identified by the first information element in the TXOP, the first AP will not execute the deactivation DUO operation. This means that if the deactivation time period overlaps with the transmission of the current DUO operation, the first AP will choose to postpone the execution of the deactivation operation to avoid affecting the ongoing communication. This approach can avoid abruptly deactivating the DUO operation during its execution, prevent communication interruptions due to improper timing, and ensure that data transmission in the network is not interfered with.

[0168] Scenario 3: If the deactivation of DUO has not yet taken effect, and the first AP 101 sends a DUO activation frame to the STA 102, the DUO activation frame indicates that the first AP 101 refuses to activate the DUO operation.

[0169] In this embodiment of the disclosure, before the deactivation operation takes effect, i.e., before the deactivation time point in the first radio frame arrives, the AP can still send a DUO activation frame to the STA. In this case, the AP explicitly indicates to the STA that it refuses to activate the DUO operation by sending the DUO activation frame. Specifically, this means that before the deactivation operation takes effect, the AP can still refuse to activate the DUO operation by sending a DUO activation frame, preventing unnecessary DUO operations from starting.

[0170] Step 404, AP 101 determines the second radio frame, the second radio frame identifying: the first BSS parameter after deactivating the DUO operation of the BSS where the first AP 101 is located, and / or the second BSS parameter after deactivating the DUO operation of the BSS where the other APs are located.

[0171] Wherein, the first BSS parameter or the second BSS parameter includes at least one of the following:

[0172] Bandwidth (BW), maximum physical protocol data unit (PPDU) length, and maximum media access control protocol data unit (MPDU) length.

[0173] In this embodiment of the disclosure, after the first AP deactivates the DUO operation of the BSS where the first AP is located, and / or deactivates the DUO operation of the BSS where other APs are located, it determines the second radio frame.

[0174] This radio frame is used to identify the first BSS parameters after deactivating the DUO operation of the BSS where the first AP is located, and / or the second BSS parameters after deactivating the DUO operation of the BSS where the other APs are located. Specifically, after deactivating the DUO operation, the operating parameters of the BSS may change, such as BW, maximum PPDU length, or maximum MPDU length. These parameters need to be updated to ensure optimal network performance. The updated BSS parameters are transmitted to the devices in the network via the second radio frame, ensuring that each device can adjust its behavior according to the latest BSS configuration. By updating the BSS parameters promptly after deactivating the DUO operation, the first AP can ensure that the devices in the network always use the most appropriate configuration, avoiding the impact of old BSS parameters on network performance. This update operation helps improve the flexibility and adaptability of the network, enabling the network to respond quickly to environmental changes, optimize resource allocation, and improve the overall stability and efficiency of the network.

[0175] Step 405, AP 101 sends the second radio frame; correspondingly, STA 102 receives the second radio frame.

[0176] In this embodiment, the AP sends the second radio frame, and the STA receives the second radio frame. This process indicates that after deactivating the DUO operation, the AP transmits updated BSS parameters to the STA via the second radio frame. These parameters may include network configuration items such as bandwidth, maximum PPDU length, and maximum MPDU length. After receiving this information, the STA can adjust its communication settings according to the new BSS parameters to better adapt to the network environment and improve performance. Through this information transmission, it is ensured that the STA can obtain the latest BSS configuration in a timely manner, avoiding network performance impacts due to parameter mismatches. This mechanism guarantees coordination and synchronization between devices, ensuring that each device in the network is always in an optimal working state, thereby improving overall network stability and resource utilization efficiency.

[0194] Before the start time for deactivating the DUO operation indicated by the first radio frame arrives, the DUO operation is performed in the transmission opportunity TXOP with the site equipment STA that has already activated the DUO operation;

[0195] If the time period corresponding to the DUO operation overlaps with the time period of the deactivation DUO operation indicated by the first radio frame, and the overlapping time period is within TXOP, then the first AP will not perform the deactivation DUO operation during the overlapping time period.

[0196] If the deactivation of DUO has not yet taken effect, and the first AP sends a DUO activation frame to the STA, the DUO activation frame indicates that the first AP refuses to activate the DUO operation.

[0202] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0203] Figure 6 is a second schematic flowchart illustrating a communication method according to an embodiment of the present disclosure.

[0204] As shown in Figure 6, the above method can be applied to STA 102, and the method includes:

[0205] Step 601: Receive a first radio frame; wherein the first radio frame is used to: deactivate the DUO operation of the BSS where the first AP is located, and / or deactivate the DUO operation of the BSS where other APs are located.

[0206] Step 602: Receive a second radio frame. The second radio frame indicates: the first BSS parameters after deactivating the DUO operation of the BSS where the first AP is located, and / or the second BSS parameters after deactivating the BSS where the other APs are located.

[0207] The communication method involved in the embodiments of this disclosure may include step 601 or step 602. For example, step 601 may be implemented as a standalone embodiment, step 602 may be implemented as a standalone embodiment, and steps 601+602 may be implemented as standalone embodiments, but are not limited thereto.

[0208] In some embodiments, the steps and their optional implementations in other embodiments described before or after this embodiment, as well as other related parts in the specification, can be referred to, and will not be repeated here.

[0209] In one embodiment, the first AP carries information in the first radio frame (e.g., a beacon frame, (Re)association response frame, or probe response frame) to deactivate DUO operations of the BSS where the first AP is located and / or to deactivate DUO operations of the BSS where other APs are located. This information may include, for example:

[0210] The first information element indicates the time information for deactivating the DUO operation; wherein the first information element may include an element ID, a length, and a field for carrying the deactivation time information (start time information); wherein the time information is related to TBTT (target beacon transmission time) or to the transmission period of the beacon frame, for example, it may be an integer multiple of the TBTT or the beacon frame period;

[0211] The first information field, wherein the first parameter value in the first information field is updated, indicating that the first information element is carried in the first wireless frame or in a frame after the first wireless frame; for example, the value in the BSS parameters change field or check beacon field is increased by 1, indicating that its BSS parameter has changed, and the first information element is carried in a subsequent frame or in the current frame, that is, the time information for deactivating the DUO operation.

[0212] The second information field, wherein the second parameter value in the second information field is updated, indicates that the first radio frame is used to deactivate the DUO operation of the BSS where the other AP is located; the other AP includes APs that are attached to the same multi-link access point device (AP MLD) as the first AP; specifically, the other APs can be other APs attached to the same AP MLD (belonging to transmitted BSSID or non-transmitted BSSID). Optionally, the BSS parameter change value of the per-STA profile of the multi-link element in the first radio frame is incremented by 1, and the deactivation time information is carried in the STA profile field;

[0213] The second information element identifies the DUO deactivation operation that the first AP needs to report to its neighboring AP (only if it is not attached to the same AP MLD or does not support multi-link). For example, the BSS parameter change identifier (value incremented by 1) is carried in the RNR information element of the first radio frame, and the deactivation time information can be sent by the neighboring AP via beacon frames and / or probe response frames.

[0214] In some embodiments, one or more of the following operations are performed after the first radio frame is transmitted:

[0215] Before the deactivation takes effect, the first AP and its STA that have already activated DUO operations continue to perform DUO operations in TXOP;

[0216] Regardless of whether you are a TXOP holder or a Responder, if the DUO operation in the TXOP overlaps with the deactivation time, the deactivation operation will not be performed. That is, whether you are a STA or the first AP, you need to consider the deactivation effective time when performing the DUO operation.

[0217] If a DUO activation frame is sent to the STA (if it has not been activated before) before the deactivation takes effect, the AP will refuse to activate the DUO operation.

[0218] In some embodiments, after deactivation takes effect, the method further includes:

[0219] After deactivation takes effect, it may affect changes in BSS operating parameters, such as bandwidth, maximum PPDU length, or maximum MPDU length, which will require updating. For example, the first AP can determine and send a second radio frame, in which it identifies: the first BSS parameters after deactivating the DUO operation of the BSS where the first AP is located, and / or the second BSS parameters after deactivating the DUO operation of the BSS where the other APs are located.

[0220] This disclosure also proposes an apparatus (also referred to as a communication device, etc.) for implementing any of the above methods. For example, an apparatus is proposed that includes units or modules for implementing the steps performed by the terminal in any of the above methods. Furthermore, another apparatus is proposed that includes units or modules for implementing the steps performed by a network device (e.g., an access network device, a core network functional node, a core network device, etc.) in any of the above methods.

[0221] It should be understood that the division of units or modules in the above device is only a logical functional division. In actual implementation, they can be fully or partially integrated into a single physical entity, or they can be physically separated. Furthermore, the units or modules in the device can be implemented by a processor calling software: for example, the device includes a processor connected to a memory containing instructions. The processor calls the instructions stored in the memory to implement any of the above methods or to implement the functions of the units or modules in the above device. The processor can be, for example, a general-purpose processor, such as a Central Processing Unit (CPU) or a microprocessor, and the memory can be internal or external to the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuits. The functionality of some or all of the units or modules can be achieved through the design of these hardware circuits, which can be understood as one or more processors. For example, in one implementation, the hardware circuit is an application-specific integrated circuit (ASIC). The functionality of some or all of the units or modules is achieved through the design of the logical relationships between the components within the circuit. In another implementation, the hardware circuit can be implemented using a programmable logic device (PLD). Taking a field-programmable gate array (FPGA) as an example, it can include a large number of logic gates. The connection relationships between the logic gates are configured through configuration files, thereby achieving the functionality of some or all of the units or modules. All units or modules of the above device can be implemented entirely through processor-called software, entirely through hardware circuits, or partially through processor-called software with the remaining parts implemented through hardware circuits.

[0222] In this embodiment, the processor is a circuit with signal processing capabilities. In one implementation, the processor can be a circuit with instruction read and execute capabilities, such as a Central Processing Unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationships of hardware circuits. The logical relationships of the aforementioned hardware circuits are fixed or reconfigurable.
